Specification of Letters Patent.

Patented "a. I7,1918.

Application filed April 6, 1918. Serial No. 227.079.

Yo 1 17/ who; if may r'rmm'rn lie it known that l. EDWARD J. KILEY, aeitizen of the luited States. residing at ('hieago, in the eonnty ot'(ook and State of Illinois. have invented eertain new and usefullmprovements in Valves, of which the following is a speeitieation.

This invention relates to valves. and more partieularly to -valvesadapted for use in eonueetion with radiators l'or variably eontrollingthe volume of fluid to be. delivered at a predeterluined openin g ot'the valve. and has partieu lar referem-o to the types of valves eommoulyknown a. graduated" and packless valves.

()ne objeet of this invention i to produee. a valve of. the eharaeterreferred to eomprising improved means for etleetively sealing: the valiestem in all positions of the valve.

Another objeet of my invention is to provide a graduated valve embodyingimproved means for variably eontrolling the amount of tiuid deliveredthrough the vaive and an indieating ring provided with improved meansfor adjustably interlocking the same with the easing.

A further objeet of the invention is to produee an improved valve whiehwill be simple. eompaet and durable in eonstruetion. and el't'eetive andellieient in operation.

To the attainment of the ends and the aeeomplishrnent of other -new anduseful objects as will appear, the invention eon- -sists in the featuresof novelty in the eonstruetion, eombination and arrangement of theseveral parts hereinafter more fully de scribed and elanued and shown HIthe aeeoman in" drawin s illustratin the embodiment of the invention,and inwhieh Figure 1 is a eentral vertieal sectional View of a valveembodying the prineiples of my invention.

Fig. 2 is a detail seet'ional view taken on the line 2- 2 of Fig. 1.Fig. 3 is a perspective view of a" slotted Washer which is employed inthe eoustruetion disclosed.

Fig. {is a sectional view taken on the line 4-4 of Fig. 1.

Similar referent-e eharaeters denote eorresponding parts in the. variousviews.

6 valve herein diselosed eomprises a body 1, provide with an inlet andoutlet 2 and 3. respeetiu-ly. wh-ieh may he threaded as shown foreonneetion with a radiator 01 the like. The upper end 4. of the body isapertured and internally threaded for the reeeption ot' the externallythreaded sleeve 5, of the bonnet (i. whieh is provided with a shoulder7, adapted to seat against the end suri'aee ot' the body to preventleakage. For the purpose of eoutrolling or governing the amount of fluidto be delivered through the. deviee. a valve member 8. having a threadedeonneetion with the valve stem 9, is provided. 'l'hevalve member 3 ispieferahlv eonstrueted as shownand is mounted for longitudinal movementrelatively to the stem. but. interloeked against rotation relalively tothe body 1 by means of projections It) provided on the inner surfaee ofthe sleeve and grooves riphery ot' the upper portion of the valve memberH. whieh is slidably mounted in the openinglr! of the sleeve 5. Thelower portion 8' of the valve member substantially eonoidaladaptedtori'iiiperate withthe port 13 formed in a web in the easing tovariably eontrol the amount of lluid delivered through the deviee. thegreatest diameter of the portion 8' being substantiallv the same as thediameter of the port. l isposed below and in'alinement with the port 13is a second port 14 formed in a web in the easing, whieh is of smallerdimensions than the lirst mentioned port and is provided with a flaringseat 15. adapted to be engaged by I portion 8 adjaeeut its small end toprevent passage of fluid through the d-eviee. lt will thatby rotation ofthe stem 9 in one direction the valve member 9 map he moved intoengagement with the seat 15 to (lose the valve to prevent passage offluid therethrough as shown in Fig. 1. and that by rotation of the stemin the opposite direction the valve member will move out of engagementwith. the seat '15, thereby opening the valve to' permit fluid to bedelivered therethrough. The amount of fluid delivered through the,deviee is governed by the lift or the amount of movement imparted tosaid valve member, the eonodial portion 8' thereof cooperating with theport l L-to vary the etleetive opening of said port in a manner as -willbe readily understood. it will be obvious from the foregoing that onesize of valve eon- 8 is shown as 'strueted as herein deseribed andillustrated 11. formed in the pe' in shape. and isbe obvious in thedrawings may be employed to properly control the fluid supply toradiators irrespective of their size and capacity.

The valve stem 9 is rotatably mounted in a suitable aperture formed inthe bonnet (i, and is provided with a flange 16 having an annulararcuate bearing surface adapted to seat against the inner surface of theflanged cone shape sealing member 17, which is mounted in a counterboreof similar conformation formed in the bonnet, The sealing member isreferably composed of metal having softer c iaracteristies than theflange 16; such for instance as lead, tin, zinc, coper, etc., or ametallic alloy thereof, and may e secured into the counterbore bycompression or by a peening operation to secure a joint that will beproof a ainst leakage. While I have shown the mem er 17 as being securedin the valve casing, it will be obvious that it may be mounted on thevalve stem if desired, and adapted to cooperate with a bearing surfaceprovided in the casing. Positioned within the cavity 18 formed in thebonnet 6, and surrounding the stem 9, is a compression spring 19, .whichexerts a pres-- sure against the U shape washer 20 which is removablymounted in an annular groove 21, formed in the stem 9. This springconstantly urges the valve stem 9 in an upward direction and tends toyieldingly maintain the flange 16 in contactual engagement with thesealing member 17, thereby effecting a perfect seal between the two, asreadily will be understood. Adjustablymounted upon the shoulder 22,formed on the exterii r surface of the bonnet 6, is an indicating ring23 upon which in turn rests a retaining disk 24. The indicating ring 23%formed with a serrated opening adapted to the casing so as to engage theangular portioirgthereot to adjustably retain said ring in any desirableosition, as shown in Fig. {and has'a stop ug 23 preferably formed"integral therewith, for a purpose to be described crcin after. Thebonnet 6 is al'soprovide with a reduced extension or ncckQ-"r whichprojects through a suitableaperture provided in the retaining disk 24and is adaptcdto be received within the opening 26 of thecap 27, whichis mounted upon said retaining disk. The cap 27 is provided with'ahandle 28, and has a polygonal opening adapted to slidably receive theend 30, of the stem which is of similar conformation, WllPlObY arotation of the cap will impart movement to said stem. A screw 31,engaging the end of the stem and having its head disposed in acounterbore formed in the top of the cap may be employed for securingthe latter in position, and a lock washer 32, may be provided forpreventing the screw from work} ing loose. The end 30 of the stem isshown as mounted in the cap in a nmnncr to permit axial movement of thestem 5), relatively.

to said cap as the parts beer me worn by use when in service. Thisarrangement eliminates the possibility of breaking the seal around thestem and consequent leakage as the result of downward pressure on theoperating handle or on the end of the device, which is an objectionablefeature common to devices of this character. Formed inte gral .with thecap on one side thereof is an indicator 33, which is adapted to engageand cooperate with the lug 23 to determine the full open position of thevalve, while other positions of the valve may be represented by marks,as shown or otherwise.

The cap 27 may be provided with a cover 34, which can be readily removedwhen it is desired to readjust the screw'31 to coin pensate for ,wear oftheparts.

Having fully described my invention and shown one form embodying thesame, I do not wish to be limited to the details of the constructionshown, since these can be obviously changed without departing from thespirit and scope of the invention.
